Shadow

Shadows are a non-hostile non-playable Race, found only in MidnightBiomes. These jet-black beings constantly emit a thick black mist, and "speak" only with a hiss of wind. At nighttime, they are almost invisible save for their glowing-green eyes.

Encounters

Midnight Biomes

Shadows only appear in Midnight Biomes, and always near mysterious constructs decorated in creepy Shrines and Shadow Markers. These structures do not appear to have any form of living quarters, so what purpose they actually serve is a mystery. It's possible they are places of worship, except the Shadows seem very indifferent to the structures' destruction at the players' hands.

Shadows are nonviolent, and have no means of defense from hostile entities save running away (or any way to stop someone who smashes their urns and takes apart the structures). Players must exercise caution when fighting in Midnight Biomes, as Shadows are not safe from player attacks as most non-hostile NPCs are.

Trivia

The Shadows are one of only two living races that cannot be summoned as a Tenant, the other being the Penguins.

A red-eyed Dark Guard Mask exists in the game files, but is unobtainable through normal gameplay. This suggests that the Shadows were at one point meant to be able to fight back, but for whatever reason the idea was abandoned.
